ANSYS HPC for Academia

高性能计算

高性能计算(HPC)是学术界的重要考虑因素。复杂的研究项目往往涉及大型装配体仿真,甚至是整个系统仿真,为了快速获得结果,研究人员需要大量的计算资源。多核处理器目前已广泛普及,即使在笔记本电脑中也不例外,这就使得大中型数值问题的求解性能得到显著提升。ANSYS学术产品可提供两种版本,以充分满足上述HPC要求:

  • 内置HPC:对于教学、研究和辅助授权而言,HPC功能内置在学术基础授权的每个任务中。对于大多数物理求解器而言,这包括最多16个内核的共享和分布式存储器HPC功能,此外,ANSYS Mechanical、Fluent和电子求解器还支持GPU访问。
  • 附加HPC:对于研究和辅助授权而言,购买额外的ANSYS学术HPC授权可扩展内置HPC功能。对于大多数物理求解器而言,共享和分布式存储器HPC与GPU功能可进行扩展。

ANSYS学术求解器支持的HPC方法与我们商业版HPC产品的方法相同。例如,如果ANSYS学术产品包含ANSYS HFSS,那么学术版HFSS产品用户能够使用和商业解决方案一样的HPC方法。同样需要注意的是,根据不同的求解器和物理类型,可用的HPC类型也有所不同,而且不是所有的求解器都支持全部的HPC方法。如欲了解求解器对HPC的支持详情,敬请参见下列PDF手册和网页:

All the ANSYS Academic Products that bundle solvers that support HPC have 16 HPC tasks built in. These 16 HPC tasks can be used for either a CPU core or a GPU card/slot. This means that up to 16 CPU cores, or alternatively up to 8 GPU cards, can be used to accelerate simulation solution times.

Structural, Thermal and Fluids Academic Products

  • Built-in HPC capability is allocated/restricted to each task. For example, for a 25-task license of ANSYS Academic Research, each user/task can access up to 16 cores, with a maximum of 16 cores available per solution.
  • Shared memory (SMP), distributed memory parallel (DMP) and domain decomposition methods are included.
  • GPU access is enabled for ANSYS Mechanical Enterprise (using the ANSYS Mechanical solver) and ANSYS Fluent solvers. Each of the 16 built-in HPC tasks can be used for one GPU card/slot, meaning that up to 16 GPU cards/slots can be accessed per academic product license. Note that we do not restrict the number of GPU cores per GPU card/slot.
  • Frequency Sweep VT and VT Accelerator is built-in and available for the ANSYS Mechanical solver. This is a legacy HPC frequency sweep solution that has been largely replaced by ANSYS DesignXplorer and Design Point Updates.
  • The following structural, thermal and fluids solvers support HPC:
    • ANSYS CFX (SMP, DMP)
    • ANSYS Fluent (SMP, DMP)
    • ANSYS Mechanical solver (SMP, DMP, Domain Decomposition)
    • ANSYS Autodyn (SMP, DMP)
    • ANSYS Polyflow (SMP, DMP)
    • ANSYS Icepak (SMP, DMP)

Electronics Academic Products

  • Built-in HPC capability is not allocated/restricted to each task. For example, for a 25-task license of ANSYS Academic Research HF, 400 HPC tasks are built-in, so a single user can use all 400 HPC tasks, or alternatively 25 users can each use 16 cores per solution.
  • A legacy shared memory (SMP) multiprocessor capability is enabled to make use of any number of SMP cores, but does not scale well beyond 16 cores. It has been largely superseded by other HPC methods.
  • Distributed memory parallel (DMP) and domain decomposition methods are included.
  • GPU access is enabled.
  • The following electromagnetics solvers support HPC:
    • ANSYS HFSS (SMP, Domain decomposition, Distributed frequency sweep)
    • ANSYS Maxwell (SMP, Distributed frequency sweep)
    • ANSYS Designer (SMP, Distributed frequency sweep)
    • ANSYS Q3D (SMP, DMP)
    • ANSYS SIwave (SMP)
    • ANSYS TPA (MP, Distributed PKG analysis)
  • The Academic ANSYS Redhawk and ANSYS PowerArtist products do not use HPC at this time.

All ANSYS Academic Research and ANSYS Academic Associate products can extend their built-in HPC capability with add-on HPC licenses. ANSYS Academic Teaching products may not extend their built-in HPC capability. There are four types of add-on HPC product licenses:

Add-on Academic HPC Product
(per core & workgroup)

Extends the built-in HPC of the following base product(s)

ANSYS Academic Associate HPC

ANSYS Academic Associate

ANSYS Academic Associate CFD



ANSYS Academic Research HPC

ANSYS Academic Research

ANSYS Academic Research CFD

ANSYS Academic Research Mechanical

ANSYS Academic Research Autodyn

ANSYS Academic Associate Electronics HPC

ANSYS Academic Associate EM

ANSYS Academic Associate HF

ANSYS Academic Research Electronics HPC

ANSYS Academic Research EM

ANSYS Academic Research HF

One task of ANSYS Academic Research/Associate HPC extends the base HPC ability of any one of the solvers that supports HPC contained in the base product (see built-in HPC section for more details of which HPC methods are available for each solver). Each task adds another core.

Both SMP, DMP and domain decomposition methods are extended to additional cores by the add-on HPC academic products. Please see the built-in HPC section above for specifics about which bundled solvers support which type of HPC.

For the structural, thermal and fluids academic products, the add-on HPC licenses can be used to extend the GPU capability provided by the built-in HPC tasks. Each add-on HPC license (task) can be used to access either a CPU core or a GPU card/slot.
